Scientists in the Netherlands are planning to build intelligent PV devices for energy and information applications. Their intention is to make this approach a new field of PV research, whose ultimate goal is enabling solar cells to communicate with each other and with other devices, ensuring that all the generated energy ends up exactly where it’s needed, especially in the urban environment.

The election of Joe Biden as U.S. president is set to heap further pressure on Australian Prime Minister Scott Morrison to lay out a clear and firm strategy charting the nation’s transition to a clean energy future.

A Dutch-Hungarian research team has measured, for 12 years, the degradation rates of PV modules installed in an off-grid system located in Ghana. It found that the panels had an average annual decline in power yield of 3.19%.

The solar manufacturer’s impressive third-quarter gross margin is set to fall back in the current three-month window because global shortages have seen some material costs double since the world came out of Covid-19 shock.

Few doubt that aluminium frames will be a part of the solar module for some time to come. And with PV manufacturing continuing to scale, the carbon footprint of this versatile metal may prove a sustainability challenge.

Scientists in the U.S. examined the use of different conductive filler materials in a lithium-ion battery electrode, finding that adding single walled carbon nanotubes to a nickel-cobalt-manganese cathode resulted in better electrical conductivity and higher rate capability for the overall battery. The results, according to the group, could provide new insights into design of high power, high energy battery electrodes.

In an Australian first, newly re-elected Premier of Queensland Annastacia Palaszczuk has established a ministry for hydrogen in her new government. The move comes amidst a raft of recent hydrogen related policies throughout Australia and reinforces the nation’s determination to lead the global race for a hydrogen economy.

Soaring fossil fuel prices have caused the scaling back or closure of Australian mines, resulting in production and job losses at a massive scale. More recently with the added consideration of carbon emissions, energy represents both a risk and an opportunity for this sector.

Biden has made a long list of promises and commitments to the environment and future of clean energy if elected. Which of these promises could we see immediate action on and which are years down the line?

An International Energy Agency report led up by Rolf Frischknecht from Treeze in Switzerland and under the joint project management of the University of New South Wales’ José Bilbao has measured the lifecycle emissions of both residential solar PV with battery storage and gas-generated grid electricity. The results are not particularly surprising, only the Morrison Government’s ongoing obduracy is.
